capabilities – Learn how to add peak and width dimensions routinely to archive descriptions

I’ve this code which provides peak and width information for photos in posts and pages:

operate add_img_size($content material){
  $sample = '/<img [^>]*?src="(https?://[^"]+?)"[^>]*?>/iu';
  preg_match_all($sample, $content material, $imgs);
  foreach ( $imgs[0] as $i => $img ) {
    if ( false !== strpos( $img, 'width=" ) && false !== strpos( $img, "peak=" ) ) {
      proceed;
    }
    $img_url = $imgs[1][$i];
    $img_size = @getimagesize( $img_url );
      
    if ( false === $img_size ) {
      proceed;
    }
    $replaced_img = str_replace( "<img ', '<img ' . $img_size[3] . ' ', $imgs[0][$i] );
    $content material = str_replace( $img, $replaced_img, $content material );
  }
  return $content material;
}
add_filter('the_content','add_img_size');

Nevertheless, this code doesn’t add in peak and width information for any photos which can be current in tag descriptions or class descriptions.

Query: how can I edit this code in order that tag descriptions and class descriptions are additionally included within the filter/operate above and pictures in tag/class descriptions have peak and width information added routinely?

Thanks.
